Question about Televison & Video
When I push the power button or use the remote to turn the power on, the green light comes on and then goes off with the power after a second or two. The screen stays black and does not display anything.
Any ideas? When I push the power button or use the remote to turn the power on, the green light comes on and then goes off with the power after a second or two. The screen stays black and does not display anything. unplugging for two hours no help. does this model have a reset button and if so where would I find it? My problem is similar. I turn the tv on and then it will go off on its own. Sometimes in 1 to 2 seconds and sometimes within 4 to 5 seconds. I took the back off and and started playing with the power supply. When I moved it, you could hear it try to power up, but then it would shut off. I did not see a reset button anywhere. Any best guesses? My tv shows the model number as ws-65807 not the one below.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Something related to the video boards. Check all inputs first, then check ribbon cables to the video board. Be careful of high voltage if you open the cover.

This behavior could be an indicator of power supply problems or abnormal current drain from elsewhere in the set.
Modern supplies are, by design, able to shut down if voltage or currents aren't within the design limits of the circuits they are servicing.
Without some hands-on it is not possible to isolate the problem unless one of the forums deals with a series fault.
If the set had a reset button, it would be located on the outside of it where the user could reset it.
The reset buttons one finds on some sets is nothing other than a very cheap kind of thermal circuit breaker that trips when current is above its limit.
These are kind of prone to failure themselves.

You need a remote. There are places that sell them, but you can usually get by with your cable box remote or some other modestly programmable remote. It would help if you had an owner's manual. You can probably find one on line. It is a bit of a dance to make the menus work correctly.
My set is gone, but you have fairly ordinary on-screen menus. One of them is for sound on or sound off to the internals. That so that there isn't the conflict between speakers from a receiver based audio setup. You should have external speaker outlets on the set itself. If you do, plut in a speaker you're not worried about. you should get sound out from there.or use an audio out connection to a receiver, etc.

Go to PS3 / Display settings. Set superbright OFF, even if you don't have HDMI. Set Cross Color Reduction to OFF. Set Display to only one resolution, not all of them as you probably have it now. Set it ot the highest possible resolution and uncheck all other boxes. The 480i is always on by default. The issue, which was very annoying, was fixed for me. I have a mitsubishi 65 inch RP that is pretty bright on daytime/sunlight scenes, so I never thought it was the PS3, but only whet the PS3 was used did this occur. I scanned this site via google to find that nobody else appeared to have resolved this. So after some changes and testing this solution worked for me. Enjoy! - Dave Walz
P.S. I think the only real fix was to set just one display resolution, but I am now watching a movie and am not going to stop it to find out. :) That's for whomever follows this posting to find out for themselves. Either way, this is working great.

SIMPLE---GO TO EBAY--
SELECT SEARCH THEN ADVANCED SEARCH AND THEN SEARCH BY SELLER---

THEY HAVE THE CHIPS AND OTHER THINGS--also have a online catalog you can order from--usually their prices on Ebay are a bit lower than the catalog prices....
6 month warranty of the chips
IF this helps you, rate this solution as I do this here for free---they are the lowest price best source for these chips and other parts.
